Hi Eason, The fuse which keeps blowing is the ECU fuse, which means the computer isn't working. That being so, the vehicle will will not start. The starter motor problem is separate and will need the starter relay or the solenoid replaced. The fact that the fuse for the management system keep blowing means there is a short or overload of that system which must be detected urgently! (WITH ALL DUE HASTE...IF NOT SOONER) in other words it may be dangerous if you have a short, as it can cause a fire! Get it sorted asap. Regards John
It will most likely be a poor earth issue, make sure the earth lead between the battery and the body is good and clean and check the one between the body and motor. Poor earth connections cause excessive current draw and will blow fuses.
I am a mechanic,i had that same problem where my engine 20amp fuse were blowing....i fixed it...problem were a broken wire in the harnace on the side of the cylinder head....i made over $200 on that job...yahhh
Check ignition switch fuse. This
is a 20 Amps. see that it has not blown. In 2004 Fuse should be nr 8 in
the power box under the hood (newer models #24).
Once you are
sure that battery, fuse and wires are OK, check starter and ignition
switch. Check if there is 12V to starter while cranking. If there is
power and the starter motor does not turn, then the motor is gone. If
there is no power to starter motor when you crank, then the ignition
switch located inside the steering column may need replacement. Before
repairing, try reading error codes with a code scanner.
IF THE FUSE BLOWS IMMEDIATELY, THE VEHICLE HAS A SHORT IN THAT CIRCUIT. CAR WON'T RUN WITH A SHORTED ECM. CHECK THE WIRING FIRST FOR A BARE OR PINCHED WIRE.
